“One suspect in this week’s deadly Boston Marathon bombing was killed after a shootout while a second suspect is still at large and the subject of a massive overnight manhunt in Massachusetts, police said early this morning.

The man the FBI identified Thursday as Suspect 2 in photos related to the Boston Marathon bombing investigation is on the loose and is armed and dangerous, police said. He is the target of an “active search by tactical teams.”

“We believe this is a terrorist, we believe this is a man that’s come here to kill people,” said Boston Police Commissioner Ed Davis said in a brief press conference this morning.”
